In Wendy Perkin's "Critical Essay on The Poisonwood Bible" (2007), Perkins recounts events of Barbara Kingsolver's The Poisonwood Bible in a manner that provides a comprehensive overview of the plot. Perkins gives her audience a holistic overview of The Poisonwood Bible by introducing each of the Price family members and addressing how each individual deals with living in the Congo and the resulting emotional distress. Perkins carefully examines the development of each Price family member throughout The Poisonwood Bible in order to show how two thematic concepts, guilt and humility, are spread within the novel and add to its literary significance. Perkins authored this critical essay for students and other members of Kingsolver's audience who may need assistance in analyzing The Poisonwood Bible.
